DEFINITION OF TERMS

8EHQ# - This is the EPA submission number that includes a 4-digit month and year followed by a 5-digit number assigned sequentially from the year 1977, followed by a sequence letter ( “A” for the initial submission and “B”, “C”, “D”, etc. for supplemental submissions) (8EHQ-MMYY-XXXXX A). Supplemental means that it is a follow-up to an earlier submitted report.
Supplemental submissions reflect the month and year logged in but retain the same 5-digit sequential number as a link to the initial submission. 8EHQ number is a useful reference to request a copy of a submission.
FYI (For Your Information) submissions are the voluntary adjuncts of 8(e)s. The FYI# is similar to that for 8(e) described above (FYI-MMYY-XXXXX A). The submitter either judges that the information is not reportable under TSCA 8(e) reporting requirements or is not subject to TSCA 8(e) reporting but wants to share the information with EPA (and the public) on a voluntary basis.

NOTE that OPPT routinely sends follow-up requests to 8(e) submitters. Other EPA programs and other federal agencies can ask OPPT to request follow-up information as well.

CHEM Name - This is the name used by the submitter.

CAS No. - The Chemical Abstracts Service Number. Use of the term "CBI" indicates that the submitter is claiming the identity of the chemical to be confidential business information. This claim can be challenged in some cases, and users should notify EPA if they wish to pursue the chemical identity.

Description - A general description of the type of study or information submitted, but not study results. A PDF electronic copy of the submission is attached.
